Gas treatment

Natural gas extracted from the fields contains particulates in the form of inclusions, heavy hydrocarbons condensate, water vapours and in some cases hydrogen sulphide and carbon dioxide. To prepare gas for transportation and to protect equipment against the corrosion Salavat Catalyst Plant adsorbents are used.

Raw materials extracted from oil, gas and condensate wells represent by itself a polyphase multicomponent mixture. Oil gas, natural gas and gas condensate extracted from the wells are moisture saturated and may contain significant amount of acid gases (СО2, H2S), organix sulfur compounds and other impurities that may lead up to gas hydrates formation and equipment corrosion. One of the safe ways to solve these problems is to use adsorption method in gas treatment.

Adsorbents of Salavat Catalyst Plant allow effectively perform of the following tasks:

  • Dehydration of natural gas and assosiated petrolium gas;
  • Dehydration and stripping of natural gas at pre-transport gas treatment units;
  • Natural gas and assosiated petrolium gas dehydration with simultaneous purification from carbon dioxide;
  • Natural gas dehydration and purification from carbon dioxide, hydrogen sulfide and other componenets;
  • Gas condensate dehydration and purification from carbon dioxide, hydrogen sulfide and other componenets;
  • Natural gas and assosiated petrolium gas purification from sulfur containing substances;
  • Natural gas purification from mercury.

Sorbents of Salavat Catalyst Plant are notable for its high performance in nuisance components removal and for its high mechanical reliability.
